The Kinetix 5700 platform was built specifically to address those constraints at scale — and the \u003cstrong\u003e2198-D020-ERS3\u003c\/strong\u003e is the 5.5 kW dual-axis inverter at the heart of that system.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTwo fully independent servo axes.

That model works fine at low axis counts, but it does not scale well. A twelve-axis machine using single-axis drives means twelve separate drive modules, twelve sets of power connections, twelve separate safety wiring runs, and twelve devices to configure and commission individually. Cabinet width grows linearly with axis count, and so does every associated cost.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Kinetix 5700 platform reorganizes this around a shared DC bus architecture. A single DC bus supply module — a 2198-Pxxx shared bus converter — provides the rectified DC bus power for an entire group of inverter modules. The 2198-D020-ERS3 is one of those inverter modules: it draws from the shared DC bus, generates its own PWM output voltages for two motor axes independently, and communicates back to the ControlLogix or GuardLogix controller over EtherNet\/IP.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe economic effect is significant. Two axes in 55 mm of panel width, sharing a single bus connection. Compared to two standalone single-axis drives handling the same load, the Kinetix 5700 dual-axis approach reduces panel space, reduces bus wiring, and consolidates safety architecture across both axes into a single module.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFor machine builders targeting high axis counts — packaging lines, printing machines, tire building systems, diaper manufacturing, converting equipment — this architecture can reduce panel size by a third or more compared to equivalent single-axis installations.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eERS3: What the Safety Suffix Means\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe \"ERS3\" suffix in the catalog number identifies the integrated safety version of this drive. It means two things in practice.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFirst, the drive carries \u003cstrong\u003ehardwired Safe Torque Off (STO)\u003c\/strong\u003e — a safety-rated function that removes the electrical supply to the motor drive transistors, preventing the drive from generating torque, without requiring the drive to be powered down. STO is the standard mechanism for implementing safe stop functions per IEC 62061 and EN ISO 13849-1.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSecond, the STO on this module is rated to \u003cstrong\u003eSIL CL3\u003c\/strong\u003e (Safety Integrity Level Claim Limit 3) per IEC 62061 and \u003cstrong\u003ePLe Category 3\u003c\/strong\u003e per EN ISO 13849-1. These are the highest safety levels applicable to a servo drive's stop function. They allow the 2198-D020-ERS3 to be used in safety applications where a single component failure must not lead to loss of the safety function — including machinery guarding, collaborative robot safety zones, and press\/clamping applications.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBeyond hardwired STO, the ERS3 designation also enables \u003cstrong\u003eintegrated safety over EtherNet\/IP\u003c\/strong\u003e — safety I\/O data flowing through the same network connection as the motion commands, using CIP Safety protocol. This allows a GuardLogix controller to command and monitor the drive's safety state through the same EtherNet\/IP connection used for motion, eliminating dedicated safety wiring between the controller and drive for axis-level safety functions.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eSingle-Cable DSL Feedback: One Wire from Drive to Motor\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eConventional servo motor wiring runs two cables between the drive and motor: a power cable (carrying the three-phase motor voltage) and a separate feedback cable (carrying encoder signals back to the drive). On a twelve-axis machine, that is twenty-four cable runs instead of twelve.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe \u003cstrong\u003eDSL (Digital Servo Link) single-cable feedback\u003c\/strong\u003e system supported by the 2198-D020-ERS3 eliminates the separate feedback cable entirely. Encoder data is transmitted digitally over the same cable as the motor power conductors, using the motor cable's shield as the return path for the feedback signal. The result is one cable per motor instead of two — half the cable tray space, half the connector count at the cabinet penetrations, and significantly reduced wiring time during machine build and commissioning.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFor the encoder itself, DSL provides multi-turn absolute position data over the single cable, meaning the drive knows motor position at power-up without requiring a homing cycle. This is particularly valuable in applications where powered-off position changes can occur (suspended loads, spring-loaded mechanisms, web tension systems) and where re-homing after power interruptions is operationally disruptive.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 2198-D020-ERS3 also supports \u003cstrong\u003eHiperface\u003c\/strong\u003e encoder protocol for compatibility with motors using that feedback standard.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eLoad Observer: Tuning-Less Commissioning\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eServo drive commissioning traditionally requires measuring or estimating the mechanical load parameters — primarily inertia ratio — and then tuning velocity and current loop gains accordingly. For machines with variable or poorly characterized loads, this process can consume significant commissioning time and may require iteration as the machine load changes with product changeover.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Kinetix 5700's \u003cstrong\u003eLoad Observer\u003c\/strong\u003e technology changes this. The drive continuously estimates the load torque in real time using an observer algorithm running in the 1,000 Hz current loop, and uses that estimate to compensate for load disturbances before they affect velocity. In practice, this means the drive can achieve stable, high-bandwidth velocity control across a wide range of inertia ratios without manual tuning of the velocity loop gains — the system adapts.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe practical benefit during commissioning is that bringing up a new axis can be as simple as setting motor nameplate parameters, enabling the Load Observer, and verifying operation — rather than iterating through gain adjustments. On a twenty-axis machine, the cumulative time saving is substantial.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eVelocity and Current Loop Performance\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 2198-D020-ERS3 closes its \u003cstrong\u003ecurrent loop at 1,000 Hz\u003c\/strong\u003e and its \u003cstrong\u003evelocity loop at up to 400 Hz\u003c\/strong\u003e.

The 2198-D020-ERS3 is an inverter module — it requires DC bus power from a compatible Kinetix 5700 shared bus converter (2198-Pxxx series) or a regenerative bus supply.
